SIGTERM + Rails + mysql？

Question

我突然开始在应用程序中遇到很多SignalException:SIGTERM异常，显然是来自mysql。堆栈跟踪，如

vendor/rails/activerecord/lib/active_record/connection_adapters/abstract_adapter.rb:217
vendor/rails/activerecord/lib/active_record/connection_adapters/abstract_adapter.rb:217:in `log'
vendor/rails/activerecord/lib/active_record/connection_adapters/mysql_adapter.rb:323:in `execute'
vendor/rails/activerecord/lib/active_record/connection_adapters/mysql_adapter.rb:608:in `select'
vendor/rails/activerecord/lib/active_record/connection_adapters/abstract/database_statements.rb:7:in `select_all_without_query_cache'

或

vendor/rails/activesupport/lib/active_support/buffered_logger.rb:63
vendor/rails/activesupport/lib/active_support/buffered_logger.rb:63:in `add'
vendor/rails/activesupport/lib/active_support/buffered_logger.rb:71:in `debug'
vendor/rails/activerecord/lib/active_record/connection_adapters/abstract_adapter.rb:196:in `log_info'
vendor/rails/activerecord/lib/active_record/connection_adapters/abstract_adapter.rb:218:in `log'
vendor/rails/activerecord/lib/active_record/connection_adapters/mysql_adapter.rb:323:in `execute'
vendor/rails/activerecord/lib/active_record/connection_adapters/mysql_adapter.rb:608:in `select'
vendor/rails/activerecord/lib/active_record/connection_adapters/abstract/database_statements.rb:7:in `select_all_without_query_cache'

我有点迷惑了。你知道从哪里开始挖掘吗？

Answer 1

您在什么平台上运行，在哪个版本的MySql上运行？听起来像是mysql客户端库或mysql服务器可能坏了。另外，这是一个新的应用程序，还是已经运行了一段时间没有问题的应用程序？

重新安装MySql可能是您最好的机会，但在此之前，请尝试使用替代的mysql适配器: mysql2和ruby-mysql。你可能会有一点运气，这将节省大量的时间和麻烦。
